fThe invention relates to railway rolling stock and more particularly tohopper cars, and consists in a novel hopper and hopper doorconstruction. This application constitutes a division of our copendingapplication Serial No. 671,854, filed May 19, 1933 now Patent No.2,042,151, dated May 26, 1936.

One of the objects of the invention is to provide a hopper carconstruction with large capacity hoppers arranged to discharge thecarload between the rails or outside of the rails, as desired.

Another object of the invention is to provide a simple, effective dooroperating mechanism which eliminates winding shafts, chains, ratchets,etc., and includes simple, rugged parts formed integrally with thedoor'and hopper.

These and other detailed objects as will be referred to later areattained by the structures i1- lustrated in the accompanying drawings,in which- Figure l is a top view of the hopper portion of a carembodying one form of the invention.

Figure 12 is a transverse section through a modified constructionillustrating a different center sill and door arrangement.

In the construction shown in Figures 1 to 11, in- 5 elusive, theunderframe comprises a box section center sill'having side walls I, abottom wall 2 and a convex top wall 3, and including outwardly anddownwardly inclined webs 43 forming the inner sides of the hoppers. Theunderframe includes side sill-like elements I having as integral partsthereof downwardly and inwardly inclined webs 44 forming the hopperouter sides.

The underframe is mounted upon the trucks (not shown but indicated bythe wheels 12) in any ordinary manner. At the center of the car is aPatent No. 2,042,1

central transom-like structure 45 comprising spaced upright webs andinclined arched or inverted V-shaped top webs. Between the transom 45and each sloping end wall 49 is an intermediate tie 52.

Transom 45 has an ofiset depending triangular lower portion 46 offsetoutwardly of the discharge opening and terminating in a bearing 41 for adoor mounting pivot 4|. The inclined end wall 49 includes a similartriangular extension 50 terminating in a bearing 5| for the other doorpivot 4|.

Preferably, all of the parts referred to above are cast intergrally witheach other whereby maximum strength for a given amount of material ispossible and the labor and material required for assembling separatelyformed parts is eliminated and the necessity of frequent inspection andtightening in order to maintain the rigidity of the structure isavoided.

Each door includes a convexly arched top plate 40, curved about an axiscoinciding with the door pivots 4|, and side plates 42 depend from theouter edges of top plate 49 and converge towards a line substantiallybelow the level of the door pivots. The door may be tilted in eitherdirection from the hopper closing position, shown in Figures 3 and 6, toa position in which one of the side plates forms a continuation of thehopper inher side 43 or to a position in which the other side plate 42forms a continuation of the hopper outer side 44. The ofiset portions oftransom 45 and end wall 49 have arched upper elements corresponding tothe arch of the door, and the lower portion of intermediate tie 52 has asimilar arcuate section accommodating the arched top plate of the door.

The outer end wall 39 of each door (Figures 8-11) is provided withextensions 39a projecting at each side beyond sides 42 and having anintegral gear or rack 54 and the vertical Web 48 adjacent hopper endwall 49 has enlarged portions 55 for journaling a shaft 56 for the worm51 which meshes with the gear 54 whereby the door may be oscillated ineither direction to open, toeither dumping position, or to closedposition.

An arcuate reinforcing flange 58 rigidifies the end of the door andprotects the teeth of gear 54, and the ends of this flange are turnedinwardly, as at 59, to form stops for abutting a lug 60 on the web 43 tolimit the movement of the door. The lowermost portion of wall 49 isoflset, as indicated at 6!, to accommodate the end of the door similarlyto the offsetting of projection 46 on the center transom. The stops 59are spaced substantially sidewardly of the door side walls 42 so thatthe door will be in the full open position when either stop 58 engagesthe center stop 65 (See right hand side of Figure 3.)

By casting the door top plate, side plates, pivot bearings, and gearteeth as a unit, and by casting the hopper end wall 49, web 48, bearings55 and lug 60 as a unit, the structure is simplified and made veryrugged so as to adequately withstand the forces incident to the roughhandling of heavy material which characterizes the use of cars of thistype. As previously indicated, assembling and maintenance costs areminimized.

Figure 12 illustrates a modified structure in which the top plate 68 ofthe door corresponds to the top plate of the door shown in Figure 3, butthe door side plates 69 merge with each other immediately below the dooraxis IE! and a downwardly projecting flange H forms a hopper extensiondeflector which serves to clear the rail, when the contents of thehopper are discharged, irrespective of the direction of the discharge.

Various other modifications and details of the hopper wall and doorconstruction may be made without departing from the spirit of theinvention and the exclusive use of all such modifications iscontemplated.

What is claimed is:

1. In a hopper car, downwardly converging side walls, triangular shapedend walls extending therebetween, the lower portions of said end wallsbeing ofiset outwardly of the hopper discharge opening, the upperelements of said oliset portions being arched between the sides of thedischarge opening, and a door extending between said end walls andprojecting into the offset portions thereof and having an archedformation fitting said elements and being arranged to tilt about theaxis of the arched elements to either side of the discharge opening.

2. In a hopper car, hopper side walls with spaced apart lower edgesdefining a discharge opening, a door having a plate extending betweensaid edges and mounted to tilt about a pivot paralleling said edges andbelow the same, and a web structure depending from said plate, said doorbeing constructed to move said plate beneath either of said edges and toaline said depending web structure with the corresponding hopper sidewall, said web structure extending below said pivot in either positionof said plate to support the flow of the contents of the hopper duringtheir discharge over and substantially beyond said pivot.

3. A hopper car door of the class described having an opening-closingtop plate, side plates depending therefrom and a transverse end wallbetween said side plates, a series of gear teeth formed on said end walland projecting laterally beyond the body of the door, there being aplatelike lateral projection on said wall provided with an extension ofsaid gear teeth, and a reinforcing flange extending across said wall andalong said projections.

4. A hopper car door of the class described having a series of gearteeth formed on an end thereof, said gear teeth being arranged in anarcuate contour and being integral with and projecting beyond the end ofthe body of said door, there being a plate-like member extending fromthe side of said body and similarly projecting gear teeth thereon.

5. In a hopper car, a hopper having sides and ends and a dischargeopening between said sides and ends, a door mounted to pivot about anaxis extending parallel with and between said sides, a gear member onthe end of said door and projecting therebeyond, a worm mounted on oneof the ends of said hopper and engaging said gear member to hold saiddoor in desired position and to move it to discharge position on eitherside of the hopper, a projection at the side of said door for supportingthe end teeth of said gear, a reinforcing flange on said projection, abracket on the hopper end which supports said worm, and a downwardprojection on the end of said reinforcing flange adapted to engage saidbracket so as to form a stop to limit the movement of the door.

6. In a hopper car, a hopper having inclined sides and ends forming adischarge opening between them, and downward extensions on said ends forpivotally mounting an arcuate door, a stop on at least one of saidextensions located above the pivot for said door and on a vertical lineextending through said pivot, said door having gear teeth arrangedarcuately on the end thereof, a flange on the end of said door belowsaid gear teeth, and projections on each end of said flange for engagingsaid stop to limit the movement of said door when moving in eitherdirection about its pivot.

7. In a hopper car, hopper structure with sloping side walls, doorstructure, means pivotally mounting said door structure on said hopperstructure, said door structure comprising a part for closing the hopperopening, side walls depending from said part and extending substantiallybelow said means, spaced stops on one of said structures, a stop on theother structure between said spaced stops, and means for rotating saiddoor about its pivotal mounting, said stops cooperating to selectivelyposition said door structure side walls in alinement with said hopperside walls to form extensions of the latter.

8. In a hopper car, hopper sides having a discharge opening betweenthem, body structure extending transversely of said sides and comprisinghopper end members and webs spaced therefrom, there being door pivotbearings on the lower portions of said webs and door stop elements onsaid webs above said bearings, a door having a top wall for closing saidopening and end walls extending transversely of said top wall adjacentto said web, and an individual pin seated in each of said end walls andthe corresponding bearings, there being a stop element on each of saidend walls for engaging said stop elements on said webs.
